have you ever stocked grass carp or tilapia? I would probably try stocking them instead of using chemicals. you should probably start looking into installing an aerator. I don't know much about algae control but i'm sure someone will come along that does normaly the experts are allover this kind of thing.

Thanks for the replys. I'm definitely going to look into the talapia since bass can eat them too. I dont have any other underwater grass as of now and hadn't used any pond color yet but will definitely look into that also.
